CIS eats too much CPU if uTorrent downloads at speeds ~1MB/s [NBZ]

The bug

  1. What you did: Did a very clean install of CIS. Configured it properly for a better work of torrent. Then I ran the torrent.
  2. What actually happened or you actually saw: CPU gets eaten up to 90-100% with just 2 progs working: CIS and uTorrent. uTorrent eats as usual, like 25-30% max, and the rest of CPU resources gets eaten by CIS and “system” process. That doesn’t happen if I uninstall CIS.
  3. What you expected to happen or see: I expected that CIS would work by rules and don’t track all the connections made by uTorrent.
  4. How you tried to fix it & what happened: https://forums.comodo.com/firewall-help-cis-b135.0/ I’ve tried everything your mods suggested.
  5. If its an application compatibility problem have you tried the application fixes here? No, that describes not my problem.
  6. Details & exact version of any application (execpt CIS) involved with download link: Any stable version above 2.0: http://www.utorrent.com/downloads/complete?os=win
  7. Whether you can make the problem happen again, and if so exact steps to make it happen:
    Run torrent and make it download anything at high speed.
  8. Any other information (eg your guess regarding the cause, with reasons):
    Nothing helps, I’m about to stop using CIS.
